CHKPT_BASENAME Parameter

The high-level qualifier for generating PowerExchange Condense checkpoint data set names.

Checkpoint data sets are VSAM KSDS clusters. To create the full checkpoint VSAM KSDS cluster name, PowerExchange appends Vn to the last qualifier, where n is a number from 0 to the value of CHKPT_NUM-1. By default, the names of the index and data components of the checkpoint VSAM KSDS clusters are the full cluster names with the suffix .D or .I.

CHKPT_NUM

CHKPT_BASENAME=hlq

For the hlq variable, enter a high-level qualifier for generating checkpoint data sets.

Maximum length is calculated as 41 - (CHKPT_NUM-1).

Enter the following high-level qualifier:

INFA.D.CHKPT

PowerExchange appends V0:

INFA.D.CHKPTV0

PowerExchange also appends .D because the name is for a data component of the VSAM KSDS cluster:

INFA.D.CHKPTV0.D
